In their own words
Justinmind
Justinmind is an interaction design and prototyping tool for web and mobile apps. It supports wireframes, high-fidelity prototypes and simulations, with web interactions, mobile gestures, action sequences and conditions built without code. Teams can model interactive forms, data lists and grids, while simultaneous editing and version control support shared work. UI kits, synchronized components, templates and masters provide ways to reuse design assets. Prototypes export as interactive HTML, and assets as SVG or PNG; the API can generate specification assets. Deployment options include cloud, self-hosted, desktop and mobile, and integrations include Figma, Adobe XD, Sketch, JIRA and Azure DevOps. The Free plan is $0 per editor/month and includes unlimited screens but only one project. Standard is $19 per editor/month, Professional is $29 per editor/month and Enterprise is $59 per editor/month. A 10-day trial is listed. Plans include a free option, and the product is presented for design teams, business analysts and developers working on UI assets and handoff.
